No, there isn't such a thing as a boot sector related to /boot. /boot is
sometimes taken as a distinct partition to make sure, it stays intact, even
if the filesystem of another partition is broken and therefor keeping the
system "somewhat" bootable. You usually have your kernels there...
However, that will not have any affect on performance. My "I am unsure" was
about having multiple partitions. A lot of people seem to say, that it has
advantages to use /var on a own partition for example, but I didn't try
myself.

If you need to make sure, you can live-swap you domU to another host, you
need to do that.
However, if you use GNBD for live mirror as backup purpose, you should not
put swap there. Swap needs really fast access and network-backed devices
tend not to be so fast...

No. It doesn't matter how you configure the virtual nic. But it surely makes
a difference wether you use the virtual nic with a linux bride or a real pci
nic (over pci passthrough).

I don't have VT and I don't know about XEON, but AFAIK there is a output
while booting Xen that shows processor flags and you should see it there.
Moreover, you need to have a VT-enabled bios with Intel processors, so have
a look there.

Bochs, VMWare, etc. Not with pure Xen without VT.
